Evolving the built environment for a changing world
Since 2007, Little Foot Building Analyis has worked to make homes perform better. What began as an energy-focused remodeling company has evolved into a specialized building analysis and energy rating practice.
Today, Little Foot Building Analysis focuses on diagnostics, testing, weatherization, and energy modeling. We investigate, measure, quantify, and improve building performance.
Certified through Building Performance Institute (BPI Building Analyst).
